Vorhersage von Position und Bewegung während sakkadischer und glatter AugenbewegungenA1

Projekt A1 untersucht die Dynamik und Präzision von sowohl glatten Augenfolgebewegungen als auch Sakkaden. Insbesondere wird bestimmt wie Positions- und Bewegungsinformation von bewegten Reizen integriert werden, sowohl während der Initiierung als auch der Aufrechterhaltung von glatten Augenfolgebewegungen. Gleichzeitig wird gemessen, welchen Einfluss die Ausführung dieser Augenbewegungen auf die Güte von Vorhersagen über komplexe Bewegungstrajektorien dieser Reize hat. Parallel zu den Verhaltensexperimenten werden Einzelzellableitungen in den parietalen Hirnarealen LIP und VIP durchgeführt, um das neuronale Substrat der im Verhalten gemessenen Leistungen zu bestimmen.
